Question

this is my code which is not working

 var getUpdates = setInterval(function () {  
            $.getJSON("@Url.Action("GetLists", "Home")?id=" + self.selectedboard(), function (data) {                           
                        var mapping = {
                            // only include these two properties
                            'include': ["cardlists"]
                        }
                        ko.mapping.fromJS(data, mapping, self.lists);
                        ko.applyBindings(helloWorldModel);
                    });                  
                }, 3000);

data is returning

[{"boardid":1,"boardname":"asdasd","listid":15,"listname":"asdasd","cardvisiblity":true,"showlist":false,"listremove":false,"showRenderTimes":false,"cardlists":[{"cardid":23,"cardname":"7","listid":15},{"cardid":24,"cardname":"3","listid":15},{"cardid":27,"cardname":"asdasd","listid":15},{"cardid":38,"cardname":"asdasd","listid":15}]},{"boardid":1,"boardname":"asdasd","listid":22,"listname":"asdasd","cardvisiblity":true,"showlist":false,"listremove":false,"showRenderTimes":false,"cardlists":[{"cardid":33,"cardname":"asdasd","listid":22},{"cardid":39,"cardname":"asdasd","listid":22},{"cardid":41,"cardname":"qdasd","listid":22}]},{"boardid":1,"boardname":"asdasd","listid":23,"listname":"asdasd","cardvisiblity":true,"showlist":false,"listremove":false,"showRenderTimes":false,"cardlists":[{"cardid":34,"cardname":"asdasd","listid":23},{"cardid":40,"cardname":"asdasd","listid":23}]},{"boardid":1,"boardname":"asdasd","listid":24,"listname":"asdasd","cardvisiblity":true,"showlist":false,"listr emove":false,"showRenderTimes":false,"cardlists":[{"cardid":35,"cardname":"qweqwe","listid":24},{"cardid":36,"cardname":"asdasd","listid":24},{"cardid":37,"cardname":"asdasd","listid":24},{"cardid":42,"cardname":"sdfsdf","listid":24},{"cardid":43,"cardname":"asdasd","listid":24}]}]

How can include only cardlists in the binding?

how can i exclude showRenderTimes in the binding?

Answer 1

By using include keyword you can only add any properties that is not already part of your original object.

By using ignore keyword you can specify those properties of your object that you don't want to map.

So in your case you can specify all properties that you don't want to be part of mapping and only have cardlists left there.

'ignore'

var mapping = {
    'ignore': ["boardid", "boardname","listid","cardvisiblity","showlist","listremove","showRenderTimes"]
}
 ko.mapping.fromJS(data, mapping, self.lists);
